The chemistry pun game is strong with this one! A drowning animal cries "Help! I'm dissolving!" while a bear on shore smugly replies "But bears are insoluble..." only to get schooled with "That's easy for you to say... You're not Polar."
Classic solubility wordplay that would make any chemistry professor groan with delight. "Like dissolves like" is practically tattooed on every chemist's soul - polar solvents dissolve polar solutes. Non-polar bears staying dry while polar bears... well, they're having a solubility crisis. Chemistry jokes may be sodium funny, but this one's actually good.
